In Typhoon 2001, you control the Claw. The Claw sits on the upper end (rim) of a web and can shoot down one of its lanes. A web consists of a number of lanes which are configured either as a closed loop or a open string. The Claw can only move along the rim of a web. Jumping off the rim is possible with a powerup. Your task is to defend your side of a web from the incoming attackers originating from the core. Everything is controlled by the keyboard or the mouse.
Every now and then a powerup will appear if you hit an enemy or an enemy shot. These powerups will give you additional powers and weapons. Sometimes you pick up an “Outta Here!” powerup, this gives you an instant 5000 points and starts the warp to the next level immediately.
New version was recently released with a number of changes, according to the author.
